"' Application filed July 5,

To all whom it may concern:

Be it known that I, Eniuunn H. Sana KUHL, a citizen of the UnitedStates, and a resident of Staten Island, county of ltichinond, and Stateof New York, have invented certain new and useful improvements inLooking Devices, of which the following is a specification.

Thisinvention relates to locking devices, and while or: more or lessgeneral application, is particularly designed forthe purpose of lockingsmall sales or banks such as book form banks commonly supplied by largebanking institutions to depositors for the collection of coins to beperiodically credited upon the depositors account.

his the primary object and purpose of my present improvements to providea device for the above purpose, which while exceedingly simple andinexpensive in its con struction, will be highly effective to preventopening of the bank or safe except by the custodian of the proper key.

In one embodiment of the invention I provide a locking rod rotatablymounted in any suitable manner upon opposite end walls of the safe. Uponthe hinged side or cover plate of the sate a locking arm is secured,said arm and the rod having ooacting means to retain said cover plate inclosed position. lrctr-zrably, resilient means is provided to coact withthe rod and yieldingly hold the same in locking position, said rod beingformed at one end with means for engagement by spaced lugs of a suitablekey whereby the rod may be rotated to release the locking arm on thecover plate.

It is also an object of my invention to provide a locking device of thischaracter which may be used in conjunction with such banks or safes andapplied thereto without necessitating numerous or expensive mechanicaloperations. i lllith the above and other objects in view, the inventionconsists in the improved looking device and in the form, constructionand relative arrangement of the several parts asw-ill be hereinaftermore fully described, illustrated in the accompanying drawings andsubsequently incorporated in the subjoined claims.

In the drawing wherein I have illustrated one simple and practicalembodiment of the invention and in which similar referent-c G P TIDN OFNEW YORK.

1 Fol-purposes of illustration, 1 have shown my present improvements asapplied to a coin receptacle or safe of the type generally known as abook form bank, in which the bank is provided with a body section and acover section constructed and shaped, and provided with surfaceornamentation in simulation of a book. It is, however, to be clearlyunderstood that no limitations must necessarily be implied from thedrawing, since in so far as the locking device itself is concerned, itwill be appreciated from the following description that this device isof more or less general application and might be advantageously usedas alocking means for receptacles or containers designed for many differentpurposes.

Inthe present instance, I have shown a receptacle or'container body 5having a cover plate 5 which is connected by means of suitable hinges(not shown) to the upper edge of one of the marginal walls oi the bodyThis body and the cover plate are conveniently stamped from metalsheets,

preferably of brass, and are lined upon the ;inner side faces of thewalls thereof with thin sheets of copper indicated at and lyoiiset as at9 and these oil-set portions of the lining sheet are provided withopenings 1O aitordlng bearlngs for-the ends of the locking rod 11. Thislocking rod at one side thereof has a longitudinally extending flattenedor plane face 12. Vith this flat face of the locking rod the obliquelyinclined end edge 14 of a spring tongue 13 struck from the lining sheet7 on the 1nner face of the front marginal wall of the receptacle bodycoacts to yieldingly hold the locking rod against rotation in the normalposition illustrated in Figure 3 of the draw ing.

The hinged top or cover plate 6 for the receptacle carries a locking arm15 which may be formed as an extension of the lining sheet 8 and isdisposed substantially at right angles to the plane of the cover plate.This locking arm or flange may extend longitudinally of the locking rod11 for any desired distance. As illustrated, said arm or flange is shownof somewhat less length than the length of the flattened surface 12 onthe locking rod and terminating in spaced relation to the resilientholding tongue 13.

At its free longitudinal edge the flange or arm 15 is provided with aninwardly directed angular bead 16. Vhen the top or cover 6 is moved to aclosed position upon the receptacle body the flange 15 enters the spacebetween the front vertical wall of said body section of the receptacleand the locking rod 11 and engages upon the flattened face 12 of saidrod which is disposed in the obliquely inclined plane illustrated indotted lines in Figure 2 of the drawings. The bead 16 rides upon thisflattened face of the rod as the flange 15 is forced downwardly wherebysaid rod is rocked or rotated until the inclined bead 16 is positionedbelow the lower edge of the flattened face 12. In such rocking orrotative movement of the rod 11, the upper edge of the flattened face 12bears against the inclined edge 14 of the spring tongue 13 which readilyyields under such pressure as shown in Figure 41- of the drawings.However, when the cover plate is fully closed and the bead 16 disposedin the position shown in Figure 2 of the drawing, the spring tongue 13immediately acts to return the rod 11 to its normal position as shown indotted lines in Figure 2, wherein it will be observed that the outerportion of this rod below the flattened surface 12 overlies the bead 16,thus effectually preventing the upward movement of the flange 15 andsecurely locking the cover plate in closed position.

At one of its ends the lockiiig rod 11 is provided at diametricallyopposite points with longitudinally extending grooves 17. This end ofthe rod is opposed to a disc 18 loosely mounted to rotate in an opening19 formed in the end marginal wall of the case body. At its inner sidethis disc is formed peaeee with a flange 20 overlying the edge of saidopening and at diametrically opposite points the edge of the opening isprovided with the notches or recesses 21. The disc 18 is also providedwith opposed radiallv extending slots 22 opening upon the periphery ofthe flange 20 and terminating in spaced relation to the center of thedisc. There is thus provided a central web 23 in the disc between theslots 22.

The key 24 as shown in Figure 7 of the drawing, has spaced lugs 25between which the recess 26 is formed. Pins 27 project longitudinallyfrom the lugs 25. At the outer side of each lug 25 a notch or recess 28is formed. Before the key can be inserted to rotate the rod 11 the disc18 is first rotated so that the slots 22 therein will register with thenotches 21. The key is now inserted, the pins 27 being engaged in thegroove 17 in the locking rod and the lugs 25 positioned in the slots 22of the disc. The end wall of the receptacle body is then in line withthe notches 28 of thekey so that the key may be turned to rotate the rod11 from its locking position shown in Figure 3, to the releasedposition, illustrated in Fig. 4 of the drawing. As will be obvious, theflattened or plane surface 12 on the locking rod being then disposed inparallel relation with the flange 15, said flange is released so thatthe cover or top plate 6 of the receptacle can be raised or lifted toits open position.

From the foregoing description considered in connection with theaccompanying drawing, the several features of my improved locking devicewill be clearly and fully understood. It will be appreciated that inView of the very simple form of the several elements employed, thedevice may be used in connection with collection banks or safes of thetype referred to without necessitating any radical structural changes insuch banks as heretofore manufactured or involving numerous andexpensive mechanical operations; The arrangement of the spring tongue 13with respect to the flattened surface 12 in the normal position of thelocking rod is such that attempts to move said rod to its releasingposition by means other than the proper key will be frustrated. Owing tothe very simple mechanical construction of the several elements, it isapparent that the improved locking device will possess maximumdurability and is not likely to readily get out of order.

I have herein illustrated and described one practical and satisfactoryembodiment of my present improvements, but since it is possible that theprinciples herein involved might be exemplified in other alternativemechanical constructions, it is to be understood that I reserve theprivilege of adopt ing allsuch legitimate changes in the form,
